Product Description

This zoom lens was exclusively* designed for use with digital Single-Lens Reflex (SLR) cameras and has 6.9 times high magnification zoom ratio. A Special Low Dispersion (SLD) and two pieces of aspherical glass elements produce high level of optical performance through the entire zoom range and alsothis has resulted in a compact, lightweight lens that features a length of 77.7mm (3"), maximum diameter of 70mm (2.7"), weight of 385gr (13.5oz) and filter size of just 62mm The new lens coating reduces flare and ghost, which is a common problem of digital cameras and also creates an optimum color balance This lens has a minimum focusing distance of 50cm (19.6") at all focal lengths and has maximum magnification of 1:5.3. It is equipped with inner focusing system, since the front of the lens does not rotate, "Petal-type hood" and a circular polarizing filter can be easily attached and used. This lens is also equipped with Zoom Lock Switch that eliminates "Zoom Creep" *35mm or APS SLR film cameras should not be used or image cut-off or vignetting will occur

Customer Reviews

Nice travel/all purpose lens
Okay, this is a cheap, wide angle almost superzoom lens. That said, it covers a very usable range, produces sharp images, has a solid build, and is light and easy to use. It is a good choice for a travel lens for an APS-C sensor dSLR (not for full frame). The bokeh is a little odd, but I can live with it. The AF can be a bit slow in poorer lighting (but many more expensive lenses suffer from this as well). I've not regretted the purchase. Highly reccomend.

Sigma 18-125 on an A200
I recently bought this lens to use on my Sony Alpha A200. it was a replacement for my kit lens. the quality of my copy is exceptional. it takes very sharp pictures, even in low light. i also have yet to experience any of the autofocus problems that other users have had. the autofocus on my copy is fast, smooth, and accurate. it's also quieter than my other lenses, and ALOT quieter than my Sigma 70-300. the internal focus is nice too, as it eliminates rotation of the front element.

the only thing i dont like about this lens is the design of the barrel when you zoom. it's in two separate pieces that slide in and out of each other, and it looks kind of cheap, if you ask me.

obviously this lens isn't a professional grade lens, but with SLD glass, internal focusing, and a price of 150 dollars (with express shipping), this lens is a bargain that can't be beat.

Kit Lens Killer
This lens is a quick step up or a replacement for the kit lens that accompanies new cameras. Not a great lens, since the barrel turns while focusing making it difficult to use a CPL or graduated ND filter. I would deffinetly reccomend this as a walk around or starter lens and the price can't be beat.
